Implementing Google reCaptcha in ASP.NET MVC

In this article, I have explained how we can implement new Google reCaptcha API in ASP.NET MVC Application using Google reCaptcha. Google reCaptcha helps to protect our websites from spam and abuse that restricts the automated input sent by a system and allows only input from a real human.

Let's take a look at step by step implementation of Google reCaptcha API in ASP.NET MVC application

It will open a new dialog, Select Empty Project => Check MVC checkbox under the "Add folders and references for" => click ok button.

Step 2: Now we would have to get site key and secrte key from google recaptcha, go to http://www.google.com/recaptcha then click on the top right corner Get reCAPTCHA button. Here you will get a form for Register a new site, fill the form and complete your registration. After complete your registration you will get Site key and Secret key those we will use in our application.

once you have entered the details, like you domain name and selected the Google recaptcha type, accpet the terms and Click on "Submit", on the next page you must get Site Key and Secret key, copy it we will need it later.
